Description

State switching method, mobile terminal, network equipment and communication system

This application requires the priority of the Chinese patent application submitted to the State Intellectual Property Office of China on December 29, 2018 with the application number 201811645077.9 and the invention titled "a state switching method, mobile terminal, network equipment and communication system". The entire contents are incorporated by reference in this application.

Technical field

This application relates to the field of communication technology, and in particular, to a method for state switching.

Background technique

Paging technology can refer to the process initiated by the network side to find a specific mobile terminal and notify the mobile terminal to communicate with the network side. Network paging mobile terminals can be divided into paging of mobile terminals in P state or paging of mobile terminals in IDLE state. Mobile terminals in P state include mobile terminals in cell paging state (CELL_PCH) or mobile terminals Paging state (URA_PCH) in the user registration area. Among them, the mobile terminal in the P state is paged, and the paging message sent by the network side carries the universal mobile communication system terrestrial radio access network wireless network temporary identifier (UTRAN, radio network, temporary identity, URNTI). The mobile terminal performs paging, and the paging message sent by the network side carries a temporary mobile customer identification code (temporary mobile subscriber identity, TMSI). When the mobile terminal is in the P state, it can only process the paging messages sent by the network side carrying the URNTI logo. When the mobile terminal is in the IDLE state, it can only process the paging messages sent by the network side that carry the TMSI logo, so only When the communication state between the mobile terminal and the network side remains the same, the mobile terminal can receive and process the paging message according to the carried identification after the network sends the paging message.

At present, with the development of the network, mobile terminals have evolved from single-card single-standby to dual-card dual-standby (dual sim dual standby (DSDS). The DSDS mobile terminal has two subscriber identity modules (subscriber identity modules) in its body , SIM) card, or two soft SIM cards (virtual SIM, corresponding to the SIM information in the form of software), or a SIM card with 2 copies of SIM information, two independent SIM cards, or two soft SIM cards will be described later Or a SIM card with SIM information of two users is collectively called two SIM cards. Therefore, two SIM cards not only represent two SIM cards in the form of hardware. The existing DSDS mobile terminal can have two working modes: the first is a single-pass mode, only one of the two SIM cards is in the data connection state, and the other card is in the standby state, that is, the two SIM cards Multiplexing the same radio frequency (RF) resource in the DSDS mobile terminal, the two cards share a set of radio frequency resources, there will be resource preemption. The second is the dual-pass mode, where both SIM cards can be in data connection, that is, the two SIM cards have independent RF resources. However, due to technical and cost considerations, most DSDS mobile terminals only support the first single-pass mode.

When the main card of the DSDS mobile terminal is in the IDLE state because the RF resources are preempted by the secondary card, and the network side has not yet synchronized with the state of the DSDS mobile terminal, the network side will always send a paging message carrying the URNTI logo, resulting in the main Although the card has acquired radio frequency resources, it cannot process the received paging message carrying the URNTI logo, and the problem of missed calls occurs.

Embodiments of the present application provide a method, terminal, network device, and system for state switching. After the radio frequency resource of the first user identity card is seized by the second user identity card, the first user identity card can be used according to the radio frequency resource And the occupancy of the second user ID card, control the first user ID card to remain idle or switch to the paging state, so that the communication status of the first user ID card and the network device to the first user ID card The communication status is consistent, and the problem of missed calls in some scenarios is optimized. The details are described below.

The named or numbered process steps can be implemented according to The technical order can be changed as long as the same or similar technical effects can be achieved.

The technical solutions described in this application can be applied to the 3rd Generation Partnership Project (3GPP), Wideband Code Division Multiple Access (WCDMA), and Time Division Synchronization Code Division Multiple Access (time division). synchronous code multiple access (TD-SCDMA) communication system.

The SIM card may include a global mobile communication system (global system for mobile communication, GSM) user identification module (subscriber identity module, SIM), a user identification module (user identity module, UIM) card, and a universal mobile communication system (universal mobile telecommunications system, UMTS) subscriber identification module (UMTS subscriber identity module, USIM) card or dual-mode card or embedded international mobile subscriber identity module (e-embedde sbuscriber ideanrity module, eSIM), etc., and may also include lower user identification cards of other communication systems For convenience of description, the following only uses the SIM card as an example for description.

It should be understood that the embodiments of the present application may also be used for multi-card multi-standby mobile terminals. The embodiments of the present invention only use the dual-card dual-standby mobile terminal as an example for illustration. The dual-card dual-standby mobile terminal refers to a mobile terminal having two SIM card, and the two SIM cards can be in the standby state at the same time, and they can both make/receive calls, send and receive text messages and other communication services. The dual-card dual-standby single-pass mobile terminal can support two numbers online at the same time with almost no increase in hardware cost, without manual switching by the user, but only one of the two SIM cards can use the mobile terminal Internal RF resources. It should be noted that the two SIM cards here correspond to two users, and each user includes the necessary information required for registration to the wireless communication network, such as one or more items of encryption information, identity authentication information, and authentication information. Therefore, the so-called two SIM cards may be physically independent two SIM cards in the form of hardware, or virtual soft SIM cards (SIM information in the form of software, which may be stored in the memory of the mobile terminal), or two in a hardware SIM card. A copy of the SIM information in software. It is understandable that on the basis of dual-card dual-standby, multi-card multi-standby can be further developed, that is, the situation that multiple SIM cards are in standby at the same time, it needs to be understood that multi-card multi-standby is very similar to dual-card dual-standby, and multiple SIM cards are also required To preempt radio frequency resources, when one SIM card is in data connection state, other SIM cards are in standby state, or multiple SIM cards are in standby state. Any two SIM cards in multi-card multi-standby are in dual-card dual-standby mode. Therefore, the multi-card multi-standby scenario is an extended application scenario or a specific application mode of dual-card dual-standby.

As shown in FIG. 1, it is a schematic structural diagram of a communication system provided by an embodiment of the present application. The communication system may include a mobile terminal and a network device, and the mobile terminal may include a first SIM card and a second SIM card. Only one of the card and the second SIM card can use the radio frequency resource of the mobile terminal. Furthermore, the mobile terminal has only one transmitting antenna, but there are multiple receiving antennas. When the first user ID card uses the transmitting antenna to send signals, the second user ID card cannot use the transmitting antenna to send signals, but the second user ID card can use the receiving antenna to receive signals. The wireless network device may be a base station or a base station controller, which is used to provide cellular wireless communication services for mobile terminals, and the first SIM card and the second SIM card may be attached to different base stations.

When the radio frequency resource being used by the first SIM card of the mobile terminal is preempted by the second SIM card, the communication state of the first SIM card will be switched from the paging state to the idle state. It is not consistent with the communication state of the first SIM card, that is, at this time, the communication state of the network device to the first SIM remains in the paging state. Then, when the first SIM card regains the radio frequency resource, the phone number corresponding to the first SIM card is called, and the first SIM card cannot process the paging message carrying the URNTI logo issued by the network device side because it is in an idle state, resulting in The first SIM card misses the call in this scenario.

FIG. 1 is a communication system provided by an embodiment of the present application. Based on this system, after a mobile terminal detects that a radio frequency resource is preempted by a second SIM card, it switches the communication state of the first SIM card from the paging state to the idle state. There are two scenarios, the first scenario is that the first SIM card reacquires radio frequency resources, and the second scenario is that the first SIM card has not reacquired radio frequency resources. At the same time, it should be noted that after the mobile terminal detects that the radio frequency resource is preempted by the second SIM, it can wait for a preset time and then switch the communication state of the first SIM card from the paging state to the idle state. The situation specifically introduces the state switching method provided in the embodiment of the present application.

The first situation: the mobile terminal detects that the radio frequency resource is retrieved by the first user identification card.

In some embodiments, the first SIM card obtains radio frequency resources again, and the first SIM card is in an idle state at this time, and the state switching process at this time is shown in FIG. 2.

FIG. 2 is a schematic diagram of an embodiment of a state switching method in an embodiment of the present application.

As shown in FIG. 2, an embodiment of the state switching method in the embodiment of the present application includes:

201. The mobile terminal detects that the radio frequency resource is preempted by the second SIM card.

The method described in the embodiments of the present application is applied to a communication system. The communication system includes a mobile terminal and a network device. The mobile terminal includes a first SIM card and a second SIM card. At the same time, the first SIM card and the second SIM card have only One can use the radio frequency resources of the mobile terminal. When the first SIM card uses the radio frequency resources of the mobile terminal, the first SIM card and the network device are in non-idle state communication. In the embodiment of the present application, when the first SIM card uses the radio frequency resources of the mobile terminal, the first SIM card Communicate with network equipment in paging state. At this time, the mobile terminal detects that the radio frequency resource is preempted by the second SIM card. The reason for the preemption may be that the service level on the second SIM card is higher than the service level on the first SIM card or other cause that the second SIM card preempts the radio frequency resource the reason.

202. The mobile terminal switches the communication state of the first SIM card from the paging state to the idle state.

Because the radio frequency resource being used by the first SIM card is preempted by the second SIM card, the mobile terminal switches the communication state of the first SIM card from the paging state to the idle state. The paging status includes the cell paging status (CELL_PCH) or the paging status in the user registration area (URA_PCH). At this time, the communication state of the network device has not been consistent with the first SIM, and the communication state of the network device to the first SIM card is the paging state.

203. The mobile terminal detects that the radio frequency resource is used again by the first SIM card, and then updates the cell of the first user identification card.

The mobile terminal detects that the radio frequency resource is reused by the first SIM card. For example, in step 201, the first SIM card is online, and the phone number corresponding to the second SIM card is called because the priority of the telephone service is higher than that of the Internet service Priority, so the second SIM card preempts the radio frequency resource. In step 202, the telephone service on the second SIM card ends and the radio frequency resource is released, then the first SIM card reacquires the radio frequency resource. The communication state of the SIM card has not been consistent with the communication state of the first SIM card, and is still in the paging state. When the mobile terminal detects that the radio frequency resource is used again by the first SIM card, the first user identification card is used for cell update. As an example, a specific cell update process is given below, which may include the following steps: the mobile terminal starts T316 timing TI_WAS_CSEL_OUT_OF_SERVICE and the timer of the service area. The T316 timer is a paging state out-of-service area timer. When the T316 timer runs, it allows the first SIM card to enter the out-of-service area process (OOS) in the paging communication state. The out-of-service area timer is used to start the OOS process when the out-of-service area timer expires. When the T316 timer is running and the out-of-service area timer expires, the cached out-of-service area internal messages are cleared, and the OOS process is started to perform cell update.

204. If the cell update is successful, the mobile terminal switches the communication state of the first SIM card from the idle state to the paging state.

If the cell update is successful, it means that the first SIM card and the network device have established a link, and the mobile terminal becomes a paging communication state. If the cell update fails, it means that the first SIM card and the network device have not yet established a link, and the mobile terminal maintains an idle communication state.

In the embodiment of the present application, when the mobile device detects that the first SIM card reacquires the radio frequency resource, the first SIM card is switched from the idle state to the paging state, and a specific communication state of the first SIM card is provided. In the method of switching from the idle state to the paging state, when the mobile terminal detects that the radio frequency resource is used again by the first SIM card, it updates the cell of the first SIM card. In order to make the communication state of the first SIM card consistent with the communication state of the network device to the first SIM card, both are in the paging state, in the scenario of optimizing the radio frequency resources of the first SIM card to be seized by the second SIM, the missed call problem.

FIG. 3 is a schematic diagram of a specific application scenario of the state switching method in the embodiment of the present application.

FIG. 3 describes a specific application scenario in the embodiment corresponding to FIG. 2. As shown in FIG. 3, the first SIM card in 3a is using traffic to access the Internet. As shown in 3b, when the first SIM card is surfing the Internet, suddenly The phone number corresponding to the second SIM card is called. At this time, the network device is still in the paging state, because the telephone service has a higher priority than the Internet service, the first SIM card releases radio frequency resources, the data service is suspended, the first SIM card becomes idle, and the second SIM card preempts the radio frequency Resources to make calls. As shown in 3c, the second SIM card releases the radio frequency resource to the first SIM card when the telephone service ends for 10 minutes and 15 seconds. After the first SIM card obtains the radio frequency resource again, it initiates a cell update action actively. If it fails, the first SIM card remains in the idle state. If the cell update is successful, the first SIM card becomes the same paging state as the network device side. As shown in 3d, the first SIM card is called, at this time, the network device side sends a paging message carrying the URNTI logo, the first SIM card is called, and the first SIM card receives paging status because At this time, the communication state of the first SIM card and the communication state of the network device to the first SIM card are both in the paging state, and the first SIM card successfully processes the paging message carrying the URNTI logo. It should be noted that the 10 minutes and 15 seconds listed in the embodiments of the present application are for illustration only.

In some embodiments, the first SIM card obtains the radio frequency resource again, and the first SIM card is in the paging state at this time, and the state switching process at this time is shown in FIG. 4.

FIG. 4 is a schematic diagram of another embodiment of a state switching method in an embodiment of this application.

As shown in FIG. 4, another embodiment of the state switching method in the embodiment of the present application includes:

401. The mobile terminal detects that the radio frequency resource is preempted by the second SIM card.

Step 401 in the embodiment of the present application can be understood by referring to step 201 in the embodiment corresponding to FIG. 2, and details are not repeated here.

402. The mobile terminal starts a first timer.

The first timer is preset to a certain duration, and when the mobile terminal detects that the radio frequency resource is preempted by the second SIM card, the first timer is started. The first timer may be an out-of-service area timer, and the out-of-service area timer is used to start the out-of-service area process after timeout.

403. The first timer does not expire, and the mobile terminal detects that the radio frequency resource is used again by the first SIM card.

404. The mobile terminal controls the first SIM card to remain in the paging state.

When the first timer does not expire, the mobile terminal detects that the radio frequency resource is used again by the first SIM card, then the mobile terminal controls the first SIM card to remain in the paging state, the first timer expires, the mobile terminal The communication state is switched from the paging state to the idle state.

In the embodiment of the present application, by starting the first timer, when the mobile terminal detects that the radio frequency resource is preempted by the second SIM card, it does not immediately switch the communication state of the first SIM card from the paging state to the idle state, but The method of waiting for the preset duration and waiting for the preset duration can be implemented by means of the first timer. When the first timer expires, the mobile terminal switches the communication state of the first SIM card from the paging state to the idle state.
